The only article that springs to mind came from Nature last year
(Vol 368:875-878, 28 April 1994). It's kinda close to what you want,
I think. It looks at the PI cycle in one-cell sea urchin embryos, showing
its correlation with the ca2+ cycle, but they mention at the end
about using anti-PtdInsP2. Not really Li+ at all.
oh, and the authors were Ciapa, Pesando, Wilding and Whitaker.
